One should be able to group by a specified field, and then sort the groups themselves NOT by that field but by another field. For instance, it is currently not possible to sort data by its name but order it by its date.
I think the question is more like this forum post http://www.telerik.com/forums/sort-groups-themselves-by-a-field-other-than-the-group-field-property
Thanks for the suggestion, Adam. This is something that should be supported by data-bound grouped grid. Check this demo for instance: http://demos.telerik.com/kendo-ui/grid/index When you group by Contact Title and then trigger sorting by Country (clicking the respective column's header text), it should be applied as expected. Am I missing something from your logic? It should be applicable for groups on DataSource level as well.
